Zoning Of Engineering Construction Adaptability Of The New City Of The Coastal New City Of Cao Fei Dian Area

With the rapid expansion of the urban resident population and the fast development of city, the gradual lowering of the quality of the environment also led to a number of questions. Therefore, in the new venue of the city before construction, we should proceed geological environment of their rationality and suitability assessment. It can corresponding solve the growing problem of population, resources, environmental issues, so that the development and utilization of urban space to play to the best effect.The research is depending on the project of thematic investigation and assessment of the stability in Caofeidian regional. Engineering environmental quality of evaluation study in the coastal new city in Caofeidian area are carried out in the thesis. The main results of the research are as following.1. Based on the deep drilling data, drilling data and regional engineering geological data of the coastal new city, standardized data base of the physics and chemistry index of the city is established. And under relevant information, the study of regional engineering geology, environmental geology, hydrogeology qualitative analysis carried out on the coastal new city, the site conditions of rationality and suitability analysis.2. The 3D geological model of 320 square kilometers in the coastal new city of Caofeidian is established by the GOCAD software. The sectioning and displaying in each direction of the model can implemented in the software. The bearing capacity and compressibility models of layers in variant depth are established for following zoning and evaluation.3. Based on the parameters extracted from Various impact indicators, the index system of the adequate evaluation is established and assigned. With the cluster analysis pattern recognition method to calculate the similarity of the evaluation unit. And then merge the unit into some subset one by one util the entire collection in a sets.So the new city is divided to inadequate zone, bad-adequate zone, medium-adequate zone and adequate zone. The evaluation results show that the eastern city is more adequate and the western city is worse adequate. The adequacy of each construction form is evaluated in the last part of the thesis.
